, Patented Feb. 6, 1917.

Application filed January 28, 1915. Serial No. 4,891.

To all whom it'may concern:

Be it known that I, JosnPi-r C. l-Linnrson,

a citizen of the United States, residing at Eldorado, in the county of Saline and State of Illinois, have invented certain new and clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same. s

This invention relates to pumps for supplying water from wells, and the primary object or" th invention is to provide a pump operated by compressed air for forcing Water, under pressure out of a well and into and out of a storage tank and a spigot or faucet for use.

Another object of this invention is to provide a construction as above specified, which embodies a float, and a-rock shaft, operable by the rise and fall of said float for controlling the inlet and exhaust of compressed air into a water retaining tank, for forcing the water upwardly into the storage tank and from thence out through an ordinary spigot or faucet.

With the foregoing and other objects in View this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure l is a sectional view through a well showing the improved pump applied thereto.

Fig. 2 is a cross sectional view through the operating mechanism of the pump which is positioned within the well.

Fig. 3 is a cross sectional view on the line 3-3 of Fig. 2, and

Fig. & is a fragmentary side elevation of a part of the operating mechanism of the pump. Referring more particularly to the draw ings, 1 designates an ordinary well which has a well platform 2 mounted upon the upperend and forming a cylinder therefor. The platform 2 supports a compressedair tank 3 which is operativel y connected to an air compressor 1, by a pipe 5 in which a I valve mechanism 6 is interposed for preventing the escape of air out of the retaining tank 3 through the pipe 5.

The compressed air retaining tank 3 has communication with a cylinder 7, which is positioned in the bottom of the well and which will be hereinafter more fully described, by a pipe 8.

The cylinder 7 .is suspended ,within'the well by supporting rods 9, which are secured to and depend from the platform 2.

The rods 9 are connected to transversely ex- I tending e ars 10, which are formed upon the sides of the tank 7. The tank .7 has an upstanding projection 11 formed thereupon, which is of smaller diameter than the tank itself and has its upper open end closed by a cover or lid 12. A packing washer is inserted between the inner surface of the cover 12 and the upper surface of an annular flange 1% which is formed upon the upper edge of the enlargement 11.

A collar 15 is mounted in engagement with the under surface of the flange 14, and suitable bolts 16 extend vertically through the cover 12, the washer 13, the flange 14 and collar 15, for securely clamping them together and forming a fluid and air tight connection between the cover 12 and the pr0- jection 11. v

A rock shaft 20 is supported within the extension 11 by depending brackets 21, and it has an, arm 22 connected thereto upon which arm is slidably mounted a weight 23. A walking beam 24 is also connected to and carried by the rock shaft 20 and it has a link connection by means of a link 25 and a spider 26. The spider 26 is slidably carried by rods 27 and 28, which extend vertically through the tank"? and the extension 11 and are supported thereby. The rods 27 and 28 have a second spider. 29 mounted thereupon in spaced'relation to the spider. 26.' The positioned in the path of a finger 34 which v is carried by the rock shaft 20 for movement therewith.

An air outlet pipe'35 extends downwardly tioned for engagement with the pin 37, and

the other end positioned for engagement with the-finger 34 upon the operation of the finger, as will be hereinafter more fully described. The walking beam 24 is connected by means of a rod 40 to a valve 41, which controls theassage of water through -the outlet pipe 55, and is active with each operation of the rocker shaft 20 and the walking beam 24 for permitting of the passage of water into the pipe. The valve 41 is carried by the lower end of the pipe 55, for preventing the backward flow of water through the pipe 55, should the check valve 56 fail to act."

The tank 7 is provided with an openin 44 extending through the bottom thereo which is shaped so as to form a valve seat for a disk valve 45. The disk valve 45 has a valve stem 46 connected thereto which is slidably supported by a spider 47. The spider 47. is secured to the under surface of the bottom of the tank 7. A lever 48 is pivotally connected to adepending arm 49, which is secured to thebottom of the tank 7. The lever 48 is positioned for engagement with the outstanding end 50 of the valve stem 46, for forcing the valve stem upwardly for moving the disk 45 out of the valve seat formed by the opening 44.

A rod 51 isconnected to the lever 48, and extends upwardly passing through guideways 52 which are carried by the tank 7 and out of the well through-the platform 2, having a handle formed upon its upper end to provide for the manual operation of the rod for forcing the valve disk 45 out of engagement with the valve seat to permit of the outlet of water from the tank 7 when it as to prevent the water from passing downwurdl through the pipe and into the tank,

so as tolpermit ot'. the upward [lowing of the water'through the tank when forced upwardly therein by lheinlel of ('(HlllHQSrXI/l air into the tank. The pipe has its elbow or T-pnnt .77 ronneeted thereto, to

which is connected a pipe 58. The-pipe 58 In the operation of the improved pump heretofore described: When the tank 7 is lowered in the'well, the weight of the surrounding water will lift the valve disk 45, when the air has been exhausted throu h the pipe 35, and the water will rise in tie tank 7 until air is admitted into the extension 11 through the valve 32. The weight 23 is of such nature as to hold the float 42 against movement, when it reaches the top of the cage formed by the rods 30 and the spiders 26 and 29, after which further pressure of .the water overcomes the action of the weight 23 and rises, throwing the weight over, which rocks the shaft 20 and operates the finger 34 causing the latter to strike the valve stem 33 and open the valve 32, The opening of the valve 32, will, provided the tank 3 is charged with compressed air, permit the escape of the air through the pipe -8 and into the tank 7 and upon the top of the water rising in the tank, which will force the water into theoutlet pipe 55 through the valve 41. The valve 41 is opened by the upward movement of the float 42, owing to the connection with the walking beam 24 through the medium of the rod 40. The \vater'entering the pipe 55will pass upwardly through thecheck valve 56 and into the storage tank 59, compressing the air which is in the tank. The check valve 56 will prevent the water from passing downwardly out of the tank 59 and into the tank 7, upon the release from the infiowing air pressure, and will hold the air compressed within the tank 59, retaining the water therein under pressure, so that upon the opening of the faucet 62, the water will rush out of the same under the pressure of the air Within the tank 59. The walking beam 24, the link 25 and the spider 26 form what is known as a rule joint, which, with the action of the weight, give resistance to the float, until the start to move, when the angle of the joint becomes more acute and easier of operation. The weight also loses its force as it moves upwar" ly to a position directly above the rocker shaft, so that when it starts its movement, it never stops until it reaches the terminus of its movement upon the opposite side of the rocker shaft from its normal position.

As the water is used out of the storage tank 59, and the tank 7, the floa't 42 moves ing the tankwill force the valve disk 45 upwardly andv automatically downwardlyatith the dropping of the level of the watenibut the rocker shaft. and the valve 32 are/held in operative position by the weight 23 until the float reaches the bottom of its bottom or "from" When the'air is exhausted out of the tank 7, the weight of the water surroundrefill the tank. The forcing of air into the tank,. will force the weight of the water in the' tank downwardly andautomatically force vthe valve. disk downwardly and close the opening 44.- The water flowing out of the storage tank 59 will relieve'the pressure of the air therein to be again compressed upon the forcing. into the tank of a; new supply,0f Water. K

The combination of the various parts of the pump heretofore described, forms a pump, or- Water Works that. furnishes water under pressure at the faucet '62 as long as there is compressed air in the tank 3.

' From the foregoing description taken in 1 scription,i;the prinoiple' of the-operationof connection with the" accompanying draw-. ings the-advantages'of construction and of the method of operation of the improved pumps will be appertains and, while in the foregoing/dethis invention has to be of construction, combination and arrange-' matically operating 7 readily apparent to those I skilled in the art to which this invention been described together various features of construction, it is understood that certain minor features with ment of parts may be altered tosuit practical conditions provided such alterations are comprehended within the scope of what is claimed.

What is claimed is In a pump, the combination of a tank adapted to befiinserted into a Well, an autovalve in the bottom of said tank, a compressed air tank, said well means for controlling said compressed air tank into said well tank,
